To on whom it may concern: 7

Be itknown that I, DAVID T. KENNEY, a citizen of the United States of America, and a resident of the borough of North Plainfield, in the county of Somerset and State of New Jersey, have invented certain new and useful Improvements in Separators for Apparatus for Removing Dust, of which the following is a specification.

This invention relates to separators for ap paratus for removing dust, such apparatus being more especially, but not necessarily, adapted for removing dust or dirt from surfaces such as floors, walls, and ceilings of dwellinghouses, office-buildings, factories, and warehouses, or for removing dust from rooms, chambers, furniture, fixtures, book cases or shelves, books, clothing, passenger-coaches, sleeping-cars, drawing-room cars, &c.

The object of the invention is to provide a separator for dustremoving apparatus in which the dust is separated from the air in an efficient, reliable, and practical manner.

My invention consists in certain features of construction and combinations of parts to be hereinafter described and then particularly claimed.

In the accompanying two sheets of drawings, Figure 1 is an elevation of an apparatus for cleaning or removing dust from surfaces or chambers in which is shown my improved separator in section. Fig. 2 is a plan'view of the improved separator; and Fig. 3 is a vertical central section of the same, taken at right angles to Fig. 1.

Referring to the drawings, a separator is shown consisting of a preferably cylindrical case or shell 1, which-is supported on suitable legs or standards 2, which separator is provided with a liquid-chamber 3, in which the dust which is drawn into the separator is separated from the air, as will appear hereinafter. A suction or air pump 4 is arranged at a suitable point and is connected by means of branch pipes 5 6 with a suction-pipe 7, said branch pipes leading to opposite sides of the air-chamber of the pump, so that bythe manipulation of suitable valves 8 9 the pump may be utilized either as a suction or as a compression pump. The suction-pipe leads by means of an intake-mouthpiece 10 into the upper end of the separator-casing above the water-level thereof. Below the water-level an air-inlet 11 is located, which is connected by means of a piece of flexible tubing or hose or other suitable pipe 12 with a hand or equivalent implement. with a screw-coupling 13, which screws onto a screw-threaded neck on the hand implement 14. The hand implement here shown is one of the forms shown in my copending application, Serial No. 84,058, filed November 21, 1901, and of which this is a division. Any suitable form of hand implement provided with a heador shoe 15 which is slotted to admit dust or dirt and in which a valve is arranged which may be controlled by a suitable lever 16 maybe used. The passage from the slot of the shoe or head to the flexible tube or pipe 12 is indicated in dotted lines, as is also the valve for controlling the said passage.

The separator here shown is a liquid separator which may be manufactured and sold separately from any other part of the dustremoving apparatus or plant. A funnel 17 is preferably provided through which the liquid-chamber of the separator may receive water or other suitable liquid, the said fillingfunnel being controlled by a stop-cock 18. A water-gage 19 indicates the height of the water in the casing.

In Fig. 1 the pipe leading from the hand implement 14 is connected by an elbow-coupling 20 with the casing 1, said coupling preventing the liquid in the liquid-chamber 3' from finding its way into the hand implement. Between the inlet 11 for the dust-laden air and the air-outlet -10 and below the liquidlevel there is arranged in the liquid-chamber 8 of the separator a transverse perforated plate 21, which is suitably secured in the casing. The position of the said perforated plate is preferably horizontal, as shown, so that when suction is exerted on the separator by the pump 4 and the head 15 of the hand implement 14 is applied to the surface to be cleaned the dust-laden air will be drawn into the liquid-chamber through the dust-inlet 11, and the dust being retained by the liquid in the liquid-chamber the air drawn out of the separator will be free or practically free from dust. Bubbles of dust-laden air will be formed in the liquid in the liquid-chamber, and these bubbles striking the perforated plate will be,

broken up thereby and the smaller bubbles of a size not sufiicient to carry any dust into the The hose is preferably providedupper part or air-chamber of the separator will be drawn through the perforations of the said. plate. In this way the perforated plate acts as a means for breaking up the dust-laden bubbles of air and causes all the dust to be retained in the liquid.

In the liquid-chamber of the described wet separator the water or other liquid therein becomes charged with dust and dirt and then at the desired moment the dirty liquid is permitted to flow off through the faucet 31. Should such an interval of time elapse that the dust and dirt will settle in the bottom of the casing of the separator. so as to form a deposit therein which would not of itself flow off through the faucet 31, the action ofthe pump 4 is reversed so as to force compressed air into the separator-casing 1, thereby squirting the deposit out or blowing it through the faucet 31.

The separator shown acts as a suction-reserve and equalizer for the reason that a partial vacuumis created in the air-chamber above the liquid, causing a constant and practically uniform suction on the dust-inlet head or shoe, whatever may be the variations due to friction or other possible disturbances in the pumppipe or attached parts.

What I claim as new and of my invention 1. A separator for a dust-removing apparatus. said separator consisting of a liquidchamber, a dust-laden air-inlet pipe discharging horizontally into the said chamber below the liquid-level, an air-outlet above the liquidlevel, a perforated plate located in the chamber above the air-pipe and below the normal liquid-level, and means for causing a current of air to flow through the said air-pipe, substantially as described.

2. A separator for a dust-removing apparatus, said separator consisting of a liquidchamber, a dust-laden air-inlet pipe opening horizontally through the wall of the liquidchamber below the liquid-level, a perforated plate projecting from the side of the liquidchamber, above the air-inlet and below the normal liquid-level, and means for causing a current of air to flow through the said pipe.
